Over-parametrized models

Biography

On August 24th, 2026 I successfully defended my PhD thesis. The thesis, entitled “Optimization in Modern Machine Learning: Steepest Descent Theory and Trustworthy Models” was supervised by Professor Volkan Cevher.

I received a Bachelor’s degree in Telecommunication Engineering from Sun Yat-sen University in 2020, and a Master’s degree in Machine Learning from KTH Royal Institute of Technology in 2022. From July to September 2022 I was an intern at LIONS. In September 2022 I started my PhD there.
